摘要
试验采用单因子设计,在相同基础日粮中分别添加0、25、50、75mg/kg的混合碳酸稀土组成4种日粮。20d的饲养试验结果表明,混合稀土能显著提高小白鼠的生长。与对照组相比,日粮中添加混合稀土能显著提高小白鼠的体增重(P<0.05)和采食量(P<0.05)。
Effect of mixed rare earth（RE） supplementation on growth of white mice were studied in this experiment. A single-factor randomize trial was designed. RE was supplemented at 0, 25, 50 or 75 mg/kg in the basal diets. The results indicated that RE could increase growth for white mice.The 20-day-old weight increased significantly compared control group,and showed very significantly difference for weight gain（P〈0.05） and feed intake（P〈0.05）.
